Claims.

This invention relates generally to nozzles, and more particularly it relates to improvements in nozzles of the type employed in washing dishes or the like.

An important object of the invention resides in the provision of a dish washing nozzle head provided with a storage chamber for soap chips or the like, and having easily accessible, manually controllable means for by-passing a portion of a hot water stream through said chamber when it is desired to produce a soapy water spray.

A further object is to provide an improved spray head wherein an incoming stream of water under pressure is broken up into a`relatively large number of iine streams, all of which are at substantially equal pressure.

A still further object is to provide a nozzle head with means for thoroughly mixing soap with a clear water stream to produce a soapy water spray for dish washing.

A further object is to generally improve and simplify the construction, arrangement and operation of dish washing nozzles for one or more oi the purposes mentioned, and still other objects will become apparent to those skilled in the art upon examination of the Yfollowing specification, drawings and claims.

Figure 7 is a View taken along line '1 -'1, Figure 6, certain parts being omitted.

`Figure 8 is a viewAalong lines 8 8, Figure 6.

Figure 9 is a view along line 9 9, Figure 6.

Like parts are identied by the same reference characters throughout the several views.

With reference to the embodiment of the invention as shown in Figure l, the illustrated device includes a spray head I0, having a handle I I mounted on a stem I2 on which extends integrally a bearing plug AI3 mounted within the spray head and adapted to be manually oscillated in respect vthereto for the control of valve ports later described.

The spray head comprises a generally cylindrical casting I6 having an upper wall II and an integral bearing portion I8 under wall I1 'and in which bearing plug I3 seats. Bearing portion I8 ris preferably an integral portion of casting I6. Wall Il is provided with a raised and threaded marginal rim 2li threaded to engage the complementarily threaded cup-like housing 2l to provide a chamber 22 for the storage of soap `or soap chips. The lower end of cylinder IB has a pair of spaced closures 24 and 25, respectively, removably engaged therewith to define a mixing chamber 26 within the cylinder I6, closures 24 and 25 being provided with mutually offset multiple nozzle apertures 24a and 25a, respectively. The apertures are each conically counterbored and the offset of apertures 24a from apertures 25a. is such that the projected axes of the former will preferably register with the counterbores of the latter.

The device is adapted for attachment to the hot water faucet of a kitchen sink, whereby to provide a user with means for spraying either soapy or clear water directly onto the dishes being washed. Connection to thehot water faucet is made through a flexible conduit 2l engaging the outer end of stem I2 for the conduction of water under pressure through a center bore 28 in stem I2. The water flowing through center bore 28 `is controllable through manual oscillation of 'bearing plug I3 whereby it may either all be directed into mixing chamber 26 to discharge therefrom through the nozzle apertures of closures 24 and 25 in the form oi a clear spray, or in part may be by-passed through soap chamber 22 whereby to provide a soapy solution within mixing chamber 26 for discharge through nozzle apertures 24a and 25a to produce a soapy water spray.

While handle II `and valve plug I3 are in the position shown in Figures 1, 3 and 4 to produce a soapy spray, part of the stream flowing through handle bore 28 flows through a radial plug port 3U and through aligned ports 30a and 30h in wall I'I and in flow regulator plate 29, later described, to enter soap chamber 232, from which it discharges through a transverse plug passage '3l which is aligned with suitable bearing ports vto allow flow of the soapy water into the mixing chamber 26. The rest of the incoming stream flows through an oppositely positioned radial plug port 33 and an aligned bearing port 33a. directly into the mixing chamber. When a clear spray is desired, handle I I and plug I3 are osicillated approximately degrees to close passages 30 and 3 I, and to align radial plug passage 34 with bearing port A33a to conduct the entire clear water stream into the mixing chamber.

Bearing plug I3 and bearing I8 are preferably provided with complementary tapers whereby to ensure a snug rit therebetween and to limit the extent to which the plug extends into the bearing. The terminus of plug I3 has an `outwardly extending arm 35 positioned for engagement with the pair of arms 36 within the bearing portion of cylinder I6 to limit the extent of oscillation of the plug between the positions above described. Casting i6 is provided with an outwardly extending stuing box 31 about stem I2. Stem I2 is provided with an annular rib 38 disposed within stuiiing box 31 and biased toward bearing I8 by spring 39 maintained under compression between a packing element 40 and rib 38. K

The regulating plate 29 is centrally journaled and maintained in contiguous clamped engagement with the upper surface of wall I1 by a screw 43. The plate is provided with ports which may be aligned with the inlet and outlet ports of the soap chamber or may be offset in respect thereto to limit the flow of water through the inlet and outlet ports. Adjustment of plate 29 may easily be effected when housing 2l is removed from casting I6 by loosening screw 43 and retightening the screw after the proper adjustment has been made. This plate is adjusted as desired to regulate relative flow through the soap chamber 22 in accordance with the solubility of the soap used.

rIhe function of the pair of spaced closure plates 24 and 25 each having multiple nozzle apertures with the respective apertures mutually offset is to ensure proper mixture of the soapy water with the clear water before final discharge from the device as a spray during use. Due to Y the clear water entering the chamber 26 through port 33a, and the soapy water entering through passage 3l, considerable turbulence is present to v initially mix the soapy water with the clear water throughout the chamber. Resulting mixture is discharged under pressure throrugh thef sunk portion of offset nozzle apertures 25a and partially against the'ilat, inner wall of plate 2-5, whereby the streams are individually broken up within the space between the plates with the result that a further mixture of the soap is effected prior to the nal discharge or the mixture through nozzle apertures 25a. The impingement of streams from apertures 24a upon the tapering counterbores of apertures 25a improves the quality of spray delivered from the device.

An alternate embodiment of the invention is shown in Figures 6 to 9, inclusive. In common with the device above described, the alternate device includes a spray head Illa comprising a generally cylindrical casting lBa provided with a handle l la with a longitudinal Water passage 28a leading into a mixing chamber 26 and manually controllable valve means for Joy-passing a portion of the incoming stream through to a soap chamber '22. Thedevice differs from the preferred embodiment mainly in the handle mounting and the valve'structure for controlling water flow through the soap chamber. A valve control plate 44 is centrally journaled in contiguous clamping engagement with the lower surface of wall 11a by means of a clamping bolt 45. Wall 11a is provided with an inlet aperture 46 and multiple outlet apertures 41. A spring biased I ball valve 49 is'mounted in plate 44 for engagement with port 46 when plate 44 is positioned to prevent soap mixing with the device. Plate 44 is also provided with multiple ball valves `50 positioned for engagement with outlet ports 41 when plate 44 is in a valve closing position.

Plate 44 has an inlet port 5l and outlet ports 52 which are circumferentially spaced from the ball valves and radially positioned for alignment with the inlet and outlet ports 46 and 41, respectively.

A manually operable push rod 54 having an inner offset portion 55 slotted at "56 to receive a pin 51 carried by plate 44 extends through the wall of cylinder Illia in slidable engagement therewith as by stufng box assembly 58. Rod l54 is provided with an outer knob 60 and an inner shoulder l to limit the extent of its sliding movement in respect to cylinder |6a. When the rod is fully depressed, plate 44 is 'oscillated about bolt 45 to engage ball valves 49 and'50 with ports 4'6 and 41, whereby to prevent water olw into or out of soap chamberv22. Withdrawal of rod 54 to the extent limited by collar 6l disengagesV the ball valves and aligns the valve plate inlet port 5l and outlet ports 52 with inlet port 46and outlet ports 41 of Wall 11a respectively, whereby to allow part of the stream enteringthe mixing chamber through passage 28a to be-by-passed through the soap chamber. The valve plate inlet port 5| is provided with Van elbow-like housing 62 which extends toward inlet port of passage 28a when the plate is inthis position to promote Water ow into the soap chamber. A ported regulating plate 29a is provided for the manual adjustment of water flow through the soap chamber as heretofore described. The mixing chamber is provided with spaced closures having aperture nozzles oiset to function in the manner set forth in connection with the preferred embodiment.
